Lithium Metal Batteries: Reducing Capacity and Voltage Decay of Co‐Free Li1.2Ni0.2Mn0.6O2 as Positive Electrode Material for Lithium Batteries Employing an Ionic Liquid‐Based Electrolyte (Adv. Energy Mater. 34/2020)

In article number https://doi.org/10.1002/aenm.2020018302001830, Guk‐Tae Kim, Stefano Passerini and co‐workers highlight the benefits of employing ionic‐liquid electrolytes (ILE) in combination with cobalt‐free, lithium‐rich layered oxide positive electrodes. The ILE dramatically reduces the capacity and voltage fading of Li1.2Ni0.2Mn0.6O2 by suppressing the structural decay of the Li1.2Ni0.2Mn0.6O2 cathode enabling long‐term stable cycling of lithium metal batteries.
